We support the following messengers:

When you write your message and schedule it, the app will send you a notification at the day and time of your choosing. Tap the notification and choose the messenger you'd like to use to send the message through. Done! 

Important: when you're using our Auto Send feature, your message will always be sent as a text message. This is because the other messenger systems we've mentioned above don't allow us to automatically send a message. We're as beaten up about it as you are. But still, a text message works as well. :)
